Digital BW, The Print

The numbers are written on the inkseparation image. If 100% M has the 
same density as 43% K then the number for M is 43. In other words you 
move up or down the K scale until you find a patch that matches the 
density of 100% of the ink you're working with. That K percentage is 
your value. Repeat for the other inks.

Like with the ink limits there is plenty room for error here. An 
approximate guess is enough. The linearization will take care of any 
remaining problems.
